The Trump administration has accepted a $130 million donation from an anonymous source in order to pay military service members during the ongoing government shutdown.

President Donald Trump announced the donation on Thursday, saying that “a friend” of his had made the donation. The president did not identify the donor, saying “he doesn’t really want the recognition.”

The Defense Department confirmed the donation to the Daily Beast, with chief Pentagon spokesperson Sean Parnell explaining, “The donation was made on the condition that it be used to offset the cost of Service members’ salaries and benefits.”

He noted that the donation was accepted under the Pentagon’s “general gift acceptance authority,” and added, “We are grateful for this donor’s assistance after Democrats opted to withhold pay from troops.”

Democrats were quick to criticize the payment, which is unlikely to have a substantial impact on the salaries of 1.3 million active service members, working out to roughly $100 per person.

Democratic Senator Chris Coons, top Democrat on the Senate Appropriations panel, expressed concerns about using anything other than public funds to pay service members.

“Using anonymous donations to fund our military raises troubling questions of whether our own troops are at risk of literally being bought and paid for by foreign powers,” he said in a statement.

The donation isn’t the only unorthodox source of income for the military during the ongoing shutdown.

On Wednesday, German Chancellor Friedrich Merz announced that his government had initiated a deal to ensure U.S. troops stationed in Germany remain paid during the shutdown.

“The federal government will initiate an unscheduled expenditure to ensure that October salaries are paid on time,” a government spokesperson said.
